Coordinated Roll Generation Scheduling Considering Wind Power Integration

With large scale wind power being integrated into power grid,the impact of wind power on the generation scheduling becomes a very important issue.Aiming at dealing with the uncertainties of large wind power integration,a look-ahead time window model for active power dispatch is proposed,based on the optimal power flow theory and accumulation variable method.It can realize the time decoupling of online generation dispatch.Based on that,a dynamic rolling generation scheduling algorithm is developed to solve the proposed model with the dynamic coupling constraints between multi-time stages.Simulation results show that the developed method can mitigate the impact of large wind power integration effectively and ensure the feasibility and accuracy of rolling scheduling.
